IMPROVEMENT IN DISH-WASHING MACHINES.

Specification forming part of Letters Patent No. 135,176, dated January 21, 1873.

I chine. Fig. 2 is a detail vertical cross-section of the same taken through the linel x, Fig. 3. Fig. 3 is a front view of the same, partly in section, through the line y y, Fig. 2.

Similar lettersof reference indicate corresponding parts.

My invention has for its object to furnish an improved machine for washing dishes, which shaH be so constructed as to wash the dishes quickly and thoroughly, and which shall at the same time be simple in construction and convenient in use; and it consists in the combination of the frame, the pivoted lower grates and-.their springs, the pivoted upper grates and their lock-bars, and one or more vertical partition-grates with each other for receiving and-holding the dishes; and in the combination of the ventilated base-box and ventilated drawer with the outer box, the pivoted case, and the dish-frame and its attachments, as hereinafter more fully described.

A is a box of suitable size, according to the amount of work to be done. The box A is provided with a hinged cover, B, and with a pipe, G, for the waste water to escape through into any convenient receptacle. The box A rests upon the rabbeted edges of the box D, which thus serves as a stand. The box A is made with ventilating-holes, and with its front side open to receive the drawer E, which is also made with Ventilating-holes in its sides. The box D and drawer E are made of such'a size that the said drawer may contain one or more of the dish-frames, hereinafter described. Fis a box or case lined with tin, zinc, or other suitable sheet metal, and provided. with a hinged cover, G, also lined with tin, zinc, or other suitable sheet metal, and provided with rubber packing H to make the said box water tightwhen its cover is closed. The cover G is secured in place, when closed, by hooks, as shown in Fig. 2. I is a frame fitting snugly .into the case F G. In the lower part of the frame I is placed a number of wire grates, J,

which are pivoted at one end of their side edges to the lower-side bars of the frame I, and their free edges rest upon coiled wire springs K, which rest upon and are secured to the bottom bars of said frame I. In the upper part ofthe frame I are placed a corresponding number of similar wire grates, L, which are pivoted at one end of their side edges to the top side bars of the frame I, so that the vsaid grates L may be turned up to allow plates,

platters, and other wide and shallow dishes to be inserted between the said upper and lower grates, as shown in dotted lines in Figs. 2 and 3. The upper gra-tes L are secured in place when closed down upon the dishes by pivoted bars M, which have a number of notches formed in the upper part of their forward edge to hook upon the free edges of the upper grates L and hold them down upon the dishes, the yield of the springs K allowing the said upper grates to be hooked down with sufcient closeness to hold the dishes securely. One or more spaces or compartments may be formed to receive smaller dishes by a vertical wire grate onscreen, N. The bottom of said compartments may be formed of a perforated sheet-metal plate arranged in the same manner as the lower grates J. To the ends of the case F G are attached gudgeons O, which pass through and revolve in bearings in the ends of the box A. One or both the gudgeons O are squared upon their ends to adapt them to receive a crank for revolving the case F G and its contents. One or both the gudgeons O may be provided with a notched slide, P, to be slipped upon the ends ofthe said gudgeons to prevent the case F G from turning while putting in and taking out the frame I. In using the machine, the dishes to be washed are arranged and secured in the frame I, and the said frame I is placed in the case F. A quantity of water, or soap andowater, are then placed in the case F, and the door G is closed and secured. The case F G and its contents are then revolved a few timesfirst in one direction and then in the otherwhich quickly cleans the dishes. The doorGis then unfastened, and the case F G is turned,

allowing the water to run od'. A quantity of clean water is then poured into the case F, and

the dishes are rinsed in the same manner as v they were washed, after which the rmsm g-water is emptied out in the same manner as the more compartments, lower movable pivoted grates J, springs K, upper movable pivoted grates L, pivoted hook-bars M for hooking on the upper grates L for the purpose of securing and holding the dishes, substantially as herein shown and described.

2. The combination of the revolving Watertight case F G and its attachments and frame I with its internal arrangements, With outer 1chest A, ventilated box D, and ventilated drawer E, substantially as herein shown and described, and for the purposes set forth.

JOSEPH USHER.
